.u 2b eilte/tom t may concern Be it known that fl', Fenna Jonson Jew- .ii-Ln, a citizen of the United States oi Amer ica, and resident of Ronse, inthe county of neida and State of New York, have invented a certain ne and useful Improve ment in Methods of Forming Baiiie-Walls for Boilers, of which the following is a true and exact description, reference being had to the accompanying drawings, which form a part hereof. y

My invention relates to 'the building up ci bams walls in tubular boilers and has for its object to provide a method for building up among the tubes of such boilers a strong impervious baille wall formed of tire brick molded into the place where it is to be used..

Broadly speaking, my invention consists in building up among the tubes of the boiler a mold or forni shaped and a ated to contain and form the tire brick ba e wall and such mold or form succes sive portions ci unburned and plastic fire brick material, then tainping such succes-n sive portions to force the plastic material into contact with the sides the tubes and into coherence with previously inserted portions until the mold is lled, and finally subjecting the baille wall thus built to e high temperature to convert the material into tire brick.. y By preference .l form any mold wall,

intended to form Athe permanent element of the bae, of wood and leave it in place until the heat and dame, applied for hardening the fire brick, burns it away and in the case of transverse 'bale walls form the wooden mold wall of transversely running wooden slats, one set runnin betweenl the tubes in one direction an another setl running between the tubes inan` other direction and crossing so as to form eference being now had to the drawin s my invention is illustrated and in Figure i -is a ing the construction of a' transverse bale wail across the tubes of a tubular boiler, and

, Fig. 2 is a similia` trating the construction of longitudinally gaming baa wells :nnong the tubes of the oi the mold and perspective view illustrab.

perspective view illusu A, Figi, indicates a wall extending'upbelow the tubes, as,

for instance, is the case with the beck wall of the tire boX,-BB, etc., are the boiler tubes, C is a .beile wall formed of an iron plate or plates,

passing through perforations in such plates in the usual manner. DD, slats running transversel and obliquely between the tubes B, D Il', etc., are similar wooden slats running transversely and obliquely in the other direction between the tubes and lappjing on and forming a wall with the slats l. The wall made up of the slats D and -D lies parallel with the opposite wall made up ot the plate oir-plates indicated at C, with the space between the two walls f the breadth or thickness which it is intended that the re brick of the ba'ile -wall should have. E is the plastic unburned lire brick material which I insert between the two walls of the mold through the top opening in successive and comparativel small portions, each of which is tamped a tamping ironv such as indicated at F, so as to force the plastic material to fill the mold space and to form a close contact with all sides of the tubes, and so also as to insure the A adhesion of the dilierent successive portions ofglastic material with each other.

eferringnext to Fig. 2, which illustrates the formation of baiile walls running parallel with the tubes, the mold walls are made up of wooden slats or beams indicated at o and d. The baffle walls indicated in this figure at E and E2 are formed of the same material and in the same way as described as to'Fig. 1.

When the molds have been ventirely filled with the coherent masses or layers of plastic dre brick material applied as described a fire is built in the fire box of the boiler for the purpose of heating and converting the plastic 'tix/e brick mat rial into fire brick and burningaway suc wooden mold rwalls. as have been used in its manufacture.yy Th/e temperature regulation of-'such a-re should, of course, be governed iii accordance with the well known conditions applicable to the proper heating of the material to be convrted into fire brick.

The bao walls, scribed, are stron coherent and tight, and thoroughly well a opted for either purpose. 'avmg now described my invention, what etc., are wooden formed as above dewith the tubes own by vgive, it hardness and perinanency,

I claim as new anclxdesire to secure by Letters Patent, is:- f

`1.o'lbejtiethocloi-forming batlle walls ot' refractorymaterial foitubular boilers, which consists in inclosing such material by walls, charging'repeated portions of plastic unburnetl irebrick material into said space and camping it to insure its lilling its portion of the space and its union with previously tamped portions and lnally subjecting the completed baille .Wall to heat to give it hardness and pernianency. l2. The method oli 'orniing baille Walls of refractory material for tubular boilers, which consists in inclosing a space to be lilled by such materiel by walls, in whole or in part formed of avootl, charging repeated portions of' lastio unburned fire brick material into sei space and taniping it to insure its filling its portion of tbe space amil its union with previously tamped portions and finally subjecting the completed baille wall to heat to and to burn out the wooden wall portions.

3. The method of forming transverse baffles of refractory material in tubular boilers,

a space to be filled by- -lieat to give 'it liartlne ss ai which consists in inclosing a space to be 0-- cupied by suoli baille wall betwcee:A walls intersected by the boiler tubes, t:lm=,;gjiiig repeated portions ol' unburnetl plastic tire brick material into said space :mi 'taniping saitl portions to cause it te ti l the space around the tubes and betwl ai the walls and to coliere .with ,previously liarged `portions aml subjecting the complt ,al baille wall to l perinanency.

, transverse bafl. The method of lorniii iles of refractory material ln tubular boilers, which consists in iuelosimzl a space to be occupied by suoli baille wal" between walls in-v tersectetl by the boiler tglbes, and consisting in whole or in part ol' `wooden slats inserted between tlic tubes, c trging' repeated por tions ol" unburned plis-tic lire brick material into said space and tamping saiflportions to cause it to` till the space around the tubes and between the walls :intl @obere ,with previously charged p oitons'antl. subjecting the completed baille wall to' heatto give it hardness and perinanenc)I and burn away tlie wooden slats.
